It will cover five PlayStation VR2 titles, which the article describes as first glimpses, highly anticipated third party titles, followed with an extended look at Suicide Squad: Kill the Justice League. A time table was not given for the whole presentation, but the Suicide Squad: Kill the Justice League part will be over 15 minutes.
Update: Shortly after Sony announced their State of Play, Bungie released a teaser confirming Destiny 2: Lightfall‘s launch trailer will be shown. The teaser does not show much, though it does contain spoilers for the end of this season.
Update 2: The Japanese listing confirms this State of Play will be approximately 45 minutes long. It also mentions 16 titles across PlayStation 4/5/VR2, so that should work out to 11 PlayStation 4/5 titles, and the five we previously knew about for PlayStation VR2.
